comScore MMX Ranks Top 50 U.S. Web Properties for November 2012

RESTON, VA, December 20, 2012 – comScore, Inc. (NASDAQ: SCOR), a leader in measuring the digital world, today released its monthly analysis of U.S. web activity at the top online properties for November 2012 based on data from the comScore MMX service. The beginning of the holiday shopping season unleashed millions of Americans on retail sites, driving most of the prominent online trends in November. Several categories saw double-digital traffic gains, including Toys, Consumer Electronics, Mall, Jewelry and Department Store sites. A record-breaking Powerball jackpot also had Americans eagerly visiting the Lottery/Sweepstakes category to check if they held the winning ticket.

“Online holiday promotions began in earnest almost as soon as the calendar flipped to November, as retailers hoped to draw in those ambitious early-season shoppers,” said Jeff Hackett, executive vice president of comScore. “As we moved later into the month, the promotional activity surged even higher around Black Friday and Cyber Monday as consumers spent record amounts online. Numerous retail categories saw huge gains for the month, with Toys and Consumer Electronics sites posting the sharpest month-over-month gains.”
